ATTACHMENT FOR PHONOGBAPHS.

To all whom'z't may concern:

Be it known that 1, Louis H. :HAYS, a citizen of the-United States,residentof Cleveland, county of Cuyahoga, and State of Ohio, haveinvented a new and useful .lmprovement in Attachn'ients for Phonographs,of which the following is a specification, the principle of theinvention being herein explained and the best mode in which l havecontemplated applying that principle, so as to distinguish it from otherinventions.

This invention relates to phonogra or talking machines, particularly totalking machines of the disk record type such as the Victor andColumbia.

The object of the invention is the provision of a simple and inexpensiveattachment for use in connection with such machines to automaticallystop the same when the end of the record has been reached.

To the accomplishment of the above and related ends said invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims.

The annexed drawing and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstitutin however, but one of various mechanical orms in which theprinciple of the invention may be used.

In said annexed drawing: Figure 1 is a broken perspective. view of atalking machine of the type in hand, specifically a Victor Victrola,with my improved braking at- V 2 is a top plan view of such attachment;Fig. 3 is a bottom plan view of the same; Fig. 4 is a transverse sectiontherethrough on the line 4%, Fig. 2; and Fig. 5 is a perspective view ofa sound box such as is used'in machines of the class in band, togetherwith a clip mounted thereon to cooperate with my braking attaclnncnt aswill presently appear.

Referring to the drawing, particularly Fig. 1, will be seen to designatethe cabinet or box of the machine upon the top of which, mounted shownin Fig. 4, or tamiliar on a suitable turn table 1/. is a fial circulardisk record construction. This dish merely frictional rests on the tablea, being properly centered by being provided with an aperture 71 thatengages with a central pin a on such table, see Fig. l ivotally mountedadjacent to the table so as to permit its free end to swing across thedisk is the tapering arm A that communicates with the Specification ofLetters Patent. Application filed July 8, 1808.

Patented Oct. 112, 1 9ml. Serial No. 4, 12,444.

I horn of the machine, such horn being concealed in the cabinet inthe'particular machine illustrated. The outer end of the horn isprovided, among other things, with a sound box a that bears a needlethat c0- operatcs with the disk to produce the sound. in operating themachine, as will be recalled such needle is started at the outer edgeor. periphery of the disk and follows the spiral record groove until itarrives at the center.

Heretofore it ha. been a source of no small inconvenience in the use ofmachines of the class in hand to note the arrival of the needle or soundbox at the end of the record. and incidental completion of the record.in order to stop the machine, which is desirable not merely to keep themotor from running down and promptly cut ott' the sound, but also, andmore important. to prevent the tapering .rm from jumping across the diskand by engagement of the needle with the disk to damage the recordthereon.

My brake attachment comprises. then. a n'uember. designed to looselyrest on top of the disk. being held in place thereon by on gaging with acentral aperture 1' the same pm (1 that serves to locate the disk on thetable. This member, which is preferably made of metal and is circular inform. is yu'ovidcd on its under side with pads c of friction ma tcriulFig. 3, preferably suit rubber. for cu gaging with the disk. Said memberis al o provided on its upper side with a knob 1" of any suitable designwhereby the member may be houvcniently handled by the user. Pivotall vmounted on the upper face of lbc member is a catch arm c adapted in oneposition to project beyond the edge oi the ]IHlll her to engage thesound box or corrcspoudiug part of the macluuo. when such part lieswithin a 'predclcl'mlucd d stance from the center of tbedisk. springFig. 2. tends thus to position said arm. but a trip 1- serves normallyto retain the sumo in its inoperative position. 'llus trip is pro \idcdwith a pin 1' adjuslably licld thcrcm so as to project at any desireddistance bei'oud tlic mcuibcr. which pin is likewise iidaplcd to beengaged by the sound box. or prcthrably the needle borne by such box.This pin can accordingly be located so as to register quite exactly withthe termination oi the record on'thc disk. so that as the trip i carriedaround by the disk'iu the course of the lattcr's rotation it will befinally brought til up against the needle of the sound box and therebyrelease the catch arm 0 Such catch arm immediately springs intooperative position and upon the completion of the next rotation of thedisk and brake member it in turn engages the needle or preferably thesound box, the disposition of the parts being properly arranged withthis in view. \Vhere neither the needle or sound box aflord a convenientmeans for such engagement I provide a clip C in theform of an encirclingspring for the sound box, such spring clip having a projecting arm 0that will thus engage with the catch arm of the brake member G. Sincethe engagement of this brake member with the disk is frictional only,the stopping of the machine will not be sudden and sharp as where themanually operated stop regularly employed in machines of this character,is thrown into action, buta gradual braking efiect is exerted, whichbrings the motor governor, and other parts of the machine to a stopWithout shock or injury to the parts.

I do not claim broadly a brake attachment for disk talkin machines,comprising a member designed to rest on top of the disk, and means borneby'said member adapted to engage the sound box, or corresponding part ofsaid machine, as such part approaches the center of the dish andpriority thereto is hereby disclaime'd.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any one of the followingclaims or the equivalent of such;

stated means be employed. 7

I therefore particularly point out and distinctly claim my invention 1.A brake attachment fol-talking machines, comprising a member adapted toloosely rest on the record, said membei'diaving a friction surface forengaging with said record, and radially adjustable means borne by saidmember and adapted to enthe sound-box or corresponding part of saidmachine. as such part approaches the center of the record.
